diaspora-installer package results in unstartable service

[Sean O'Connell]

Installation of the diaspora-installer package on a clean, up-to-date 16.04.1 LTS server results in an app server that will not start and throws a Ruby exception. This renders the newly installed diaspora* server unaccessible.

The package installs correctly if the system has enough memory (at least 1GB). On a server with 512M memory and no swap gem compilation exhausted the system memory and the package installation failed without a clear error message as to why.

Following installation of the package, the diaspora service is started:

root@bug-test:~# systemctl status diaspora

However, the application server is not launched on localhost TCP port 3000:

Which is configured as the nginx proxy target:

root@bug-test:/etc/nginx/sites-enabled# cat pod.bugtest.lan
upstream domain11 {
        server 127.0.0.1:3000;
}

Connections to the new pod result in a 404 (see attached screenshot):

root@bug-test:/var/log/diaspora# cat error.log

The root cause appears to be a failure of the application server to start:

Hi Sean,

This team where you logged the bug was for packaging Diaspora but has not been active in ages. The people who have packaged Diaspora for Debian are not in this group, so you should really log this bug in the Debian bug tracker.

I'll notify the packager of this bug and if he wants to take ownership of this team here, I'll give it to him, otherwise I'll close this team here (if able to).

[Sean O'Connell (sdoconnell)]

Okay, thank you Jason.
